Abstract
A One-Shot receiver for indoor positioning using the GPS L1 C/A signal
is presented. It uses both coherent correlation and noncoherent integration
to achieve the low sensitivity required for indoor applications,
and includes interpolation for code delay estimation, a novel CN0
estimator, and a near-far problem mitigation technique. The impact
of the navigation message bit transitions on the sensitivity is also
studied. Live indoor environments are used to show the receiver performance.
